HUBER Unite States T t 3,080,672 DGUBLE-FG=PER=TRIGGER-ACTUATIQN CAP PISTGL Robert A. Huber, 1033 lilth, Charleston, Ill. Filed Nov. 15, 1961, Ser. No. 152,484 1 Claim. (Cl. 42-57) The present invention consists of a cap pistol which is so constructed as to successively fire two caps for each actuation of its trigger by reason of a double-firing action resulting from movement of a striking hammer between two opposed impact-receiving anvils adapted to carry caps of the explosive type.

In one preferred form of the invention, each of the impact-receiving anvils may be supplied repetitively, by cap-feeding means, with the end cap of the end strip portion of a large quantity of caps (usually arranged in the form of a spiral roll of caps stored on a corresponding mounting post means) in a magazine portion of the cap gun.

In one preferred form, the gun may simulate a pistol. However, the invention is not specifically so limited and may simulate various other forms of guns such as rifles, automatic rifles, Burp guns, submachine guns, machine guns, cannons, artillery pieces, and the like.

It is an object of the present invention to provide a gun of the type referred to above wherein a single trigger actuation and return results in a double capfiring action on two different cap-exploding anvils.

It is a further object of the present invention to provide a novel cap gun of the type referred to above including double-action cap-feeding means also operated by a single actuation and return of the trigger in a doubleaction manner such as to feed the end cap of a corre sponding supply of caps in strip form to the corresponding cap-exploding anvil.

It is a further object of the present invention to provide a novel cap gun of the character referred to above which is of extremely simple, cheap, foolproof construction such as to be conducive to widespread use thereof.

Further objects are implicit in the detailed description which follows hereinafter and will be apparent to persons skilled in the art after a careful study thereof.

For the purpose of clarifying the nature of the present invention, one exemplary embodiment is illustrated in the hereinbelow-described figures of the accompanying drawings and is described in detail hereinafter.

FIG. 1 is a reduced-size perspective view of one exemplary embodiment of the invention.

FIG. 2 is a side elevation of the form of the invention shown in FIG. 1 with the magazine access door or cover in open position to allow reloading the gun by placing new rolls of caps therein.

FIG. 3 is a side elevational view of aspect similar to FIG. 2 with certain portions on the near side partly broken away in order to show the interior of the barrel portion of the gun and interior of the handle containing the magazine portion of the gun and in order to show the operating mechanism of the gun. It should be noted that the controllably openable and closable access door or cover is completely removed from the structure in this view. This view also shows the trigger, the hammer, and the coupling means, all in the forward extreme position.

FIG. 4 is a fragmentary view generally similar to the upper right hand portion of FIG. 3 but shows the trigger and coupling means in an intermedaite spring-stretching position after the trigger has been pulled rearwardly a considerable distance but before it reaches the rearward extreme position shown in FIG. 5 and before the hammer has been rearwardly actuated.

FIG. 5 is a view similar to FIG. 4 but shows the trigger and coupling means in the extreme rearward position and also shows the hammer after it has been rearwardly actuated from the position shown in FIG. 4.

FIG. 6 is a view similar to FIG. 5 but shows the trigger and coupling means in another intermediate springstretching position between the rearward extreme position shown in FIG. 5 and the forward extreme position shown in FIG. 3. In this view the hammer is still in the rearward extreme position just prior to being actuated forwardly into the forward extreme position shown in FIG. 3.

FIG. 7 is a cross-sectional view of the complete device taken in the direction of the arrows 7-7 of FIG. 3.

FIG. 8 is a fragmnetary view, partly in elevation and partly in section, taken in the direction of the arrows 88 of FIG. 3.

FIG. 9 is a fragmentary, partly broken-away view of the connection of the linkage member to the rearward extension of the trigger and to the rotary over center means taken in the direction of the arrows 9 of FIG. 4.

FIG. 10 is a cross-sectional view of the complete device taken in the direction of the arrows 10-10 of FIG. 3.

FIG. 11 is a greatly enlarged fragmentary view illustrating the detailed structure of one of the anvil means and the outer and inner cap strip guiding means adapted. to feed a cap strip end thereonto for impact by the hammer.

Referring to the figures for exemplary purposes, one illustrative embodiment of the invention takes a typical exemplary form wherein it comprises a gun body, such as is indicated generally at 20' which, in the specific example illustrated, simulates a pistol although not specifically so limited. Furthermore, in the specific example illustrated, the barrel 22 of the gun body 20 is formed of two mating side portions 22A and 22B fastened together by suitable fastening means 21 which may com prise rivets or any other suitable type of fasteners of a mechanical, adhesive, or cohesive nature, although not specifically so limited.

The gun body 20 includes said barrel portion 22, a handle portion 23, and an actuating trigger 24 which is slidably mounted in slot aperture means 25 for move ment between a normal forward extreme position, as maintained by the trigger biasing spring 26, and a rearward extreme position under the rearward force exerted by a finger, as illustrated in FIG. 5.

It should be noted that the biasing spring 26 is mounted on a guide rod 27 positioned in a hollow chamber 28 in the barrel 22 and has its rear end attached to an upper extension member 29 of the trigger 24. The opposite end of the spring 26 is fastened as indicated at 36.

Thus rearward slidable movement of the trigger 24 extends the trigger biasing spring 26 so that it will re-' turn the trigger portion 24 to its forward position shown in FIGS. 1-3 upon release of the rearward digital force applied thereto by the trigger finger of a user of the gun.

The specific example of the gun illustrated is provided with magazine means, indicated generally at 31, and com prising the hollow chamber defined within the handle portion 23 and provided on one side thereof with con trollably openable and closable access door means 32, which is pi-votally mounted as indicated at 33 and which is provided with digitally .graspable and operable tab means 34 which is movable into stopping abutment with respect to stop means 35 when closed.

The hollow interior of the magazine 31 is provided with two interior forwardly and rearwardly spaced mounting post means 36 each adapted to rota-tably receive thereover a corresponding hollow core 37 of a corresponding roll of caps 38 and each having a free end strip portion 38E which is adapted to be moved by two different cap-feeding means, indicated generally at 39, into a position lying against a corresponding one of two forwardly and rearwardly spaced impact-receiving anvil means 40 whereby to be struck by a corresponding side of the hammer means '41 when the hammer means 41 is in either extreme striking position, both of which occur during a single rearward trigger actuation and return to the normal forward position.

In the specific example illustrated, the hammer 41 is mounted on a longitudinal lever 42 which is pivotally mounted on a pivot pin or post 43. The hammer 41 and mounting member 42 are effectively coupled with respect to the finger-actuatable trigger means 24 by coupling means, indicated generally at 44 and, in the specific example illustrated, comprising 'a rotary overcenter member 45 pivotally mounted on the mounting post or pin 43 with respect to the gun body 2%) and positioned inside of the handle portion 23 thereof for forward and rearward arcuate movement between a forward extreme position in abutment with a stop pin S, as shown in F IG,

3, and a rearward extreme position in abutment with said stop pin S as shown in FIG. 5. Said coupling means 44 also includes a linkage member 46 connected to said rotary overcen-ter member 45 at a location offset from the pivotal mounting thereof at 43; said-linkage member 46 having a portion pivotally connected to the rearward for effectively connecting the rotary overcenter means 45 to the hammer 41. Furthermore, said linkage means together with said overccnter means 45' may be said to comprise the coupling means 44 for effectively coupling the trigger 24 to the hammer 41.

In the specific example illustrated, each of the capfeeding means indicated generally at 39 for the forward and the rearward cap end strips 35E comprises a projecting arcuate finger 52 extending from the linkage member 46 carried by the rotary ovcrcenter means 45 whereby to be forwardly and rearwardly actuated therewith in a manner such as to abut and ar-cuately and upwardly advance each of the two cap end strips 335 between outer and inner cap strip guide means 53 and 54, respectively, by a distance corresponding to the space between adjacent caps C. This operation is successively performed in correlated timed relationship with respect to the rearward extension 47 of the trigger 24 by means of a pivot pin 48 V for arcuate swinging movement of said linkage member 46 in response to trigger actuation and for corresponding arcuate rotationof said rotary overcen-ter member 45 about its pivotal mounting at 43with respect to the gun body handle 23 into either of two extreme positions as shown in FIG. 3 (which corresponds to a forward trigger position) and as shown in FIG. 5 (which corresponds to a rearward trigger position). It should be understood that when the rearward actuation of the trigger 24 from the forward extreme position shown in FIG. 3 into the rearward extreme position shown in FIG. 5 occurs, the apparatus passes through an intermediate spring-stretching position such as is shown in FIG. 4. It should also be understood that when the forward return movement of the trigger 24 from the rearward extreme position shown in FIG. 5 into the forward extreme position shown in FIG. 3 occurs as a result of the action of the return spring 26, the apparatus passes through another intermediate spring-stretching position such as is shown in FIG. 6.

The coupling means 44 is also. provided with spring means 49 having one end connected to the linkage member 46, as indicated at 50, 'at a point offset from the pivotal mounting thereof at 421 by Way of the overcenter member 45 and having another end effectively connected to said hammer means 41 (and its lever or arm member 42) as indicated at 51 whereby said spring 49 will be stretched when said rotary overcenter means 45 passes through an intermediate position (as shown in FIG. 4) between the two extreme'positions comprising the forward extreme position shown in FIG. 3 and the rearward extreme position shown in FIG. 5 (the return movement intermediate spring-stretching position being shown in FIG. 6), thus providing effective biasing of said rotary overcenter means 45 toward either of said extreme forward or extreme rearward positions and thereby effectively providing forcible snap-action operation of said pivotally mounted hammer means 41 toward forward striking, contact with the forward one of said impactreceiving anvils 40 as shown in FIG. 3 or toward rearward striking contact with the rearward one of said im pact-receiving anvil means 40 as shown in FIG. 5. Of course, in normal operation the hammer will actually strike the corresponding explosive cap C at the end or" the cap strip end 38E, which lies between the anvil 46 and the'hammer 41 whereby to explode same. It should be noted that the linkage member 46 and the biasing spring 49 may be said to comprise together linkage means and striking hammer means carried thereby,

actuation of, and forward return movement of, the trigger 24 whereby each of the anvils 40 will receive the corresponding end cap C when the hammer 41 is out of engagcment therewith, and this capfeeding operation will occur bet-ween each successive impact of the hammer thereagainst. Each of the cap end strips 38E, after explosion of :the end cap C therein, is adapted to be exhausted or fed out of the gun by way of corresponding exit slots 55 and 55, where they may be removed, as desired.

description thereof set forth in this application are for the purpose of illustrating the present invention and are not to be construed as limiting the present invention to the precise and detailed specific structure shown in the figures and specifically described hereinbefore. Rather, the real invention is intended to include substantially equivalent constructions embodying the basic teachings d inventive concept of the present invention.
